The flick made more than opening nights for 2013's superhero films "Man of Steel" and "Thor: The Dark World." It's expected that "Captain America" will easily break the $100 million mark in the United States over the weekend, making it the biggest opening ever for the month of April.

The film has already made $100 million globally after debuting in Russia, Australia and China.

On Thursday, Mackie and Stan made a surprise appearance at a charity screening of the film in New York. The co-stars helped children made personal videos to send to their military parents serving overseas.

Mackie told the New York Daily News, "It's always interesting when you have someone who's missing a loved one, how much they appreciate the little things that make us realise how jaded we are. It puts things in perspective."
